Statalist: 
 
I am trying to statistically compare two logistic regression models using svy commands and have not found a way to compare the models like the lrtest would allow me to normally do with logistic regression. 
 
I know that I can run the Wald test (.test) command after each model and get F test results,and to compare constructed equations, but I do not see a way to use this to compare logistic models. 
 
Is there a way I can compare two models (one nested) using the test command to tell if there is a statistically significant difference? Or is there another command/procedure that is a better alternative?

Syntax for two models that I want to compare: 
 
svyset APSU [pweight=FAWT], strata (ASTRATUM)
xi: svy: logistic aepart i.agecat i.income i.higheduc i.raceeth2 urban i.female*married
 
xi: svy: logistic aepart i.agecat i.income i.higheduc i.raceeth2 urban i.female
